[0 all whom it may concern:

Be it known that I, ROBERT M. DIXON, a citizen of the United States, residing at East Orange, county of Essex, and State of New Jersey, have invented certain new and useful Improvements in Incandescent Gas-Larnps,

of which the following is a specification.

My invention relates to incandescent gasciass of incan escent gas-lamps which are known as inverted burners.

In ihe accompanying drawings I have shown one form of lamp in which my invention may be embodied and for the purposes of convenience have shown it as a lamp espeeially adapted for use in railway-cars where the lamps are located close to the ceiling, and i a lamp which gives a substantially maximum downward reflection of light will tionisembodied. Fi

'not desire be most eflicient.

In the drawin sfFigure I is a transverse vertical section'o a la'rnp in which my invenlIis a section through II of Fig. I. Fig. III

the lam'pon the line I of Fig. I, and

are section on the line IIIIII F1 2 IV is a sectionon the line IV IV of Fig. I1 the problem of successfully operating,

lamps of this type upon a railway-car has been considered particularly diflicult of solution, I will describe the lainp shown in the rawings as though it were simply a carlamp, butwould have it understood that I do to have my claims limited thereto.

In these drawings, aindicates what for the Want of a better term I shall describe as a center castin'g. Within this center casting is a cruciform space b for removing from the lamp the products of combustion. This cruciform space is bounded by a series of chambers 0, within which series of chambers some" of the operating arts of 'theinverted Bunsen burners are adapted to be carried. The chambers c are closedat the top to form gasways d, (see Figs. I and-1H,) to which gas 18 brought by a series of nipples e, suitably connected by means of pipes f, which are connected by a branched pipe or duct 9 to agessupply pi e h. The center casting a is shown as provi ed with a downwardly-depending flange 'i, apertured at its lower edge, as by apertures 7, for the passage e to support the support-ring k, which is shown as screwed thereon. The support.

of air and adapt ring is is shown assurmounted by a crownpiece 1, which is aperture'd laterally, as at o, for the passage of air. The centercasting is surmounted by a draft-tube or chimney p of the elongated form, which drafttube or chimney is preferably of considerable length, but is shown broken away in the drawings for the purposes of convenience.

The support-ring k is shown as provided with a depending arm q, to which is hinged an upwardly-extending arm r, which supports a bezel or globe-supporting ring 8. The bezel or globe-supporting ring 8 is provided with a spun ring t, beneath whose lower edge the abruptly inwardly turned edge u of the globe thereby. A suitable catch to is provided for '0 extends and is directly-supported,

holding the globe-supporting ring 8 in position. i

The burners which I are preferably of the form ings and have'their mixin preferably employ shown in the draw- -ch2imbers located within the spaces comprised by the chambers 'of the center casting and'projcct downwardly therefrom for a su'liicient distance to produce an eihciently-burning air-and-gas mixture and sufficiently far into the "lobe to reach about the center thereof and leave a free -or unobstructed s ace around the same.

In the re erred form of construction shown in t e drawin s a nipple 1 is screwed into the asway d and is provided with a delivery-plate 2, shown herein as centrally apertured. Threaded to the nip le 1 is a Bunsen or mixing tube 3, provided with lateral inlet-apertures 4 at a point immediately below the delivery-plate 2. The lower end of the Bunsen or mixing tube is shown as provided with an annular slot or shoulder 5, adapted for the reception of the ends of the hooks 6 of a suitable split socket 7, whose internally-projecting flange 8 embraces an outwardly turned or formed flange 9 of a tubularmantle-support 10, having a deliverytube 11 delivering intothe interior of a man tle 12 at about the center thereof, which mantle is suitably supported, as by means of an annular supporting device 13, from the mantle-so port l0. A sleeve or reflector 15 is adapts toslide freely upon the Bunsen tube 13. This sleeve is referahly tapered from the top downward y and serves the triple purposes,first, of protecting the Bun:

sen tube from undue heat; second, of serving as a reflector, and, th rd, by means of a tapering annular recess 16 in its lower end causing the HOOKS 6 to be securely engaged with the slot or shoulder 5.

The' detailed col action of the mantlesupporting device ll be obvious from an inspection of Fig. I, wherein one of the mantles is shown in slde view as in position on the Bunsen tube. The other mantle is shown in side view as ready to be put into position, and the third mantle is shown as in section to fully and in detail illustrate the construction and operation of the parts.

It will be understood that the gas which I contemplate employing in the lamp shown in the drawings is rintsch gas and ordinarily is supplied to the lamp under a pressure or several atmospheres, which is reduced by a suitable regulatorsay a regulator of the ordinary rintscn type. the air need not necessarily be brougnt into the lamp under pressure, as the rush of the gas under pressure will cause an influx of air. As is well unde1'- stood, the gas enters the gasway d, passes through the nipple 1 to the distributingplate 5, which, as aforesaid, is centrally apertured, and thence to the Bunsen tube or mixing-chamber 3 The air enters the lamp through the apertures 0 in the side of the cap or crown-piece, is conducted into the cha1nbers c, which surround the Bunsen tube, and thence passes the apertures 4 in the Bunsen tube, where the mixing takes place. The products of combustion are removed from the lamp through the cruciform chamber or channel 6 of the center casting, being drawn upward by the suction produced by the elongated dratttubc or casing p.

Having described my invention, what I claim, and desire to secure by Letters Pat cut, is
